Chancroid Outbreak investigation Journal article Absence of human yaws and detection of Haemophilus ducreyi in skin ulcers of school children near wildlife protected areas in Tanzania https://papers.globalinfectiousdisease.com/research/articles/10-1371-journal-pntd-0014567-1cb182d0/ https://papers.globalinfectiousdisease.com/research/articles/10-1371-journal-pntd-0014567-1cb182d0/ Tue, 15 Sep 2026 00:00:00 GMT The findings suggest interruption of human yaws transmission in the studied regions, while highlighting Haemophilus ducreyi as a cause of non-genital skin ulcers in Tanzanian children and underscoring the need for continued surveillance in a One Health context.
